|Recursion and Higher-order Functions - slide 3 : 35|
Recursive functions are sufficient - but typically memory inefficient - for programming of an iterative process.
Tail recursive functions in Scheme are memory efficient for programming of any iterative process.
Tail recursion is a variant of recursion in which the recursive call takes place without contextual, surrounding calculations in the recursive function.
In a tail recursion function the recursive call is a tail call (see next slide)
